Ralph Wuerthner d8c33d32a4 [S390] zcrypt: Add additional card IDs to CEX2C and CEX2A 
Add support for new micro code load of CEX2C and CEX2A adapters,
which uses different IDs.  This patch just adds the IDs to the
existing drivers.

*
* NOTE: please refer to the comments preceding this structure
* for the implementation details for the contents of the
* block
*
* ICARSACRT
* Perform an RSA operation using a Chinese-Remainder Theorem key
* This takes an ica_rsa_modexpo_crt struct as its arg.
*
* NOTE: please refer to the comments preceding this structure
* for the implementation details for the contents of the
* block
*
* ZSECSENDCPRB
* Send an arbitrary CPRB to a crypto card.
*
* Z90STAT_STATUS_MASK
* Return an 64 element array of unsigned chars for the status of
* all devices.
* 0x01: PCICA
* 0x02: PCICC
* 0x03: PCIXCC_MCL2
* 0x04: PCIXCC_MCL3
* 0x05: CEX2C
* 0x06: CEX2A
* 0x0d: device is disabled via the proc filesystem
*
* Z90STAT_QDEPTH_MASK
* Return an 64 element array of unsigned chars for the queue
* depth of all devices.
*
* Z90STAT_PERDEV_REQCNT
* Return an 64 element array of unsigned integers for the number
* of successfully completed requests per device since the device
* was detected and made available.
*
* Z90STAT_REQUESTQ_COUNT
* Return an integer count of the number of entries waiting to be
* sent to a device.
*
* Z90STAT_PENDINGQ_COUNT
* Return an integer count of the number of entries sent to all
* devices awaiting the reply.
*
* Z90STAT_TOTALOPEN_COUNT
* Return an integer count of the number of open file handles.
*
* Z90STAT_DOMAIN_INDEX
* Return the integer value of the Cryptographic Domain.
*
* The following ioctls are deprecated and should be no longer used:
*
* Z90STAT_TOTALCOUNT
* Return an integer count of all device types together.
*
* Z90STAT_PCICACOUNT
* Return an integer count of all PCICAs.
*
* Z90STAT_PCICCCOUNT
* Return an integer count of all PCICCs.

* ICAZ90STATUS
* Return some device driver status in a ica_z90_status struct
* This takes an ica_z90_status struct as its arg.
*
* Z90STAT_PCIXCCCOUNT
* Return an integer count of all PCIXCCs (MCL2 + MCL3).
* This is DEPRECATED now that MCL3 PCIXCCs are treated differently from
* MCL2 PCIXCCs.
